【摘要】 针对大型汽轮机组数字式电液调节系统复杂,难以评价状态的问题,在分析反映系统运行状态各因素的基础上,首次提出了基于变权综合的数字式电液调节系统状态评价方法。该方法充分利用设备运行参数、状态监测参数和故障统计参数,实现了不同层次系统或设备的状态评价。实例计算表明,该方法可行有效,评价结果可为下一步的维修决策提供科学依据。更多还原

【Abstract】 Aiming at large-size steam turbine DEH governing system is complex and difficult to evaluate their conditions, a method of variable weight synthesizing condition evaluation of DEH system is firstly proposed on the basis of analysis on the condition effecting factors of DEH system. By fully using the operating parameters, condition monitoring parameters and operation statistic parameters, the conditions of equipment in different levels are evaluated. It is shown by the instance that this method is feasible and effective, the evaluated results can be used as a support next in making scientific maintenance decisions.更多还原
